For more than twenty years Echard resided in Lincolnshire, chiefly at Louth, and wrote a number of works. On 24 April 1697 he was installed prebendary of Louth in the cathedral of Lincoln, and on 12 August 1712 archdeacon of Stow. In or about 1722 Echard was presented by George I to the livings of Rendlesham and Sudborne in Suffolk. There he lived in bad health for nearly eight years. He died at Lincoln, while on his way to Scarborough for the benefit of the waters, on 16 August 1730, and was buried in the chancel of St. Mary Magdalen's Church on the 29th of the same month.

He translated Terence, part of Plautus, D'Orleans' History of the Revolutions in England, and made numerous compilations on history, geography, and the classics. His chief work, however, is his The history of England: from the first entrance of Julius Caesar and the Romans to the end of the reign of King James the first containing the space of 1678 years. (1707–1720). It covers the period from the Roman occupation to his own times, and continued to be the standard work on the subject until it was superseded by translations of Rapin de Thoyras's French Histoire d'Angleterre ("History of England").
